Diagnostic toolbox – An overview of a vibration analyst’s skillsets [Keynote speaker | Conférencier invité]

This presentation will discuss the many skillsets useful in the everyday tasks of a vibration analyst.  Whether performing route collection, data analysis or problem diagnostics, complementary skills like thermodynamics, materials resistance, principals of electricity and instrumentation, and understanding of process are an important complements to vibration knowledge and certifications. This conference will also look at the diagnostic of lubrication induced vibration.  While commissioning a first generation new design, audible noise could be heard from a distance indicating there was an undesired problem with a mechanism.  Using vibration analysis to quantify the problem and identify frequencies emitted, multiple tests were performed to understand the phenomenon in order to come up with a solution that would allow the machine to operate quietly, as expected with a new machine. The presented diagnostic will show how a team effort with multiple experts in different fields took several days to identify the source of the excitation, the proposed solution and end result.

Boite à outils de diagnostic – Un survol des multiples compétences d’un analyste de vibration [Conference | Conférence]

Dans cette présentation, on discutera des maintes compétences utiles pour les tâches journalières d’un analyste de vibration.  Que ce soit des prises de données de routes vibratoires, d’analyse de données et de diagnostic de problème, plusieurs connaissances telles que la thermodynamique, la résistance de matériaux, les principes d’électricité et d’instrumentation et les connaissances du procédé, sont d’importants atouts à la théorie de vibration et les certifications. Cette conférence présentera aussi un diagnostic de vibration causé par la lubrification.  Pendant la mise en service d’un nouveau concept, un bruit acoustique se fit entendre, laissant croire qu’un problème était présent sur un mécanisme.  Des relevés vibratoires ont permis de quantifier le problème et d’identifier les fréquences prédominantes, tandis que d’autres tests ont permis de mieux comprendre le phénomène présent afin de proposer une solution qui a réduit les niveaux vibratoires. Ce diagnostic montrera comment le travail d’une équipe multidisciplinaire a pris plusieurs jours à identifier la source d’excitation, la solution proposée ainsi que le résultat final.

Advanced diagnostics: a stepped approach [Keynote speaker | Conférencier invité]

In the current maintenance and reliability landscape, our industries are technology rich, with many tools and ‘smart systems’ to utilize.  The focus has become symptom based, monitoring and forecasting EOL for components.  At times, we lose focus of the ‘big picture’ and how different components interact and impact each other.  Advanced Diagnostics is the deeper look for cause and effect, and where unwanted input energy enters the system, not solely focusing on the ‘weak link’ where failure often occurs. We will  walk through a stepped approach, to determine the proper test scope, testing techniques and a few real world examples, from symptoms, failed correction attempts, application of Advanced Diagnostic Techniques, the results and implemented corrections.

Vibration Characteristics of Thermally Cycled Graphene Nanoplatelet (GNP) Reinforced 3D-Fiber Metal Laminates (3D-FML) [Conference | Conférence]

Harsh environmental conditions may cause materials to corrode and eventually fail, or even worse, it can be coupled with undesirable vibration in mechanical systems, resulting in premature failure of the system. Such combined loading scenarios are often encountered by transport vehicles (i.e., airplanes’ cabin, train and automobiles’ components). Today, fiber metal laminates (FMLs) and sandwich composites are often used in the fabrication of various components of transport vehicles. Therefore, it is of paramount importance to study the static and dynamic characteristics of such materials under combined loading scenarios and ensure their durability and safety. A recently introduced class of 3D fiber metal laminate (3D-FML) in our research group has shown exemplary mechanical response characteristics; however, the vibration characteristic of this novel hybrid material system under harsh environmental conditions has not been studied.  Therefore, exploring the effect of environmental parameters on the frequency response of this class of materials shapes the main objective of this research. Specifically, the main goals of this research are to characterize and understand the frequency response of 3D-FMLs under thermal fatigue and attempt to improve their vibration response by incorporation of an effective solution. To do so, 3D-FMLs specimens are exposed to combined thermal and humidity cycles. Subsequently, the vibration characteristics of the system are experimentally evaluated. An attempt is also made to improve the damping characteristics of the material system by incorporation of graphene nanoplatelet (GNP) within the interface layers of the hybrid system. It is also demonstrated that recently developed nondestructive techniques can be effectively used to assess the influence of environmental conditions on the static and dynamic behaviour of 3D-FMLs and evaluate their potential degradation under thermal fatigue.

Solving the Dirichlet Problem for vibration of Parallelogram-Shaped Membrane using Method of Partial Domains [Conference | Conférence]

In this study, the Dirichlet boundary problem for vibration of a parallelogram-shaped membrane is solved. The simplicity and transparency of the proposed procedures allow one to clarify the specific features of some state-of-the-art approaches to solve similar problems of mathematical physics. For many types of domains, including a wide range of non-canonical ones, the use of the concept of a general solution of the boundary value problem makes it possible to construct a numerical-analytical solution to the problem. In this case, sets of partial solutions for the basic equations of mathematical physics are used. The main idea is to indicate effective ways to determine arbitrary coefficients and functions that are part of a general solution. The conventional approach for deriving numerical-analytical solutions is used based on the mean square deviation minimization and collocation methods.

New Hydroelectric Unit Trips on High Vibrations during Cold Startup [Conference | Conférence]

A hydroelectric unit was experiencing vibration trips during cold startup at the generator guide bearing since commissioning in 2014. The author at the time identified that the vibration signature indicated that the unit is most likely misaligned. However, the OEM did not agree with the prognosis. The original proposal by The OEM was to increase the vibration trip levels at the generator guide bearing to alleviate the trips during cold startup. The author rejected the proposal because it did not address the root cause of the excessive shaft relative displacement levels. After four years of negotiations with the OEM and several vibration measurements. The OEM concluded that the main cause could be excessive generator guide bearing clearances and a reduction of the bearing clearances should alleviate the vibration trips. The authors rejected any reduction of bearing clearances prior to investigating the alignment of the unit. The author believed that reduction of bearing clearances with a misaligned unit could be detrimental to the bearings. This paper will discuss the findings and vibration data collected by the authors during and after commissioning. The paper will demonstrate the reasoning on how the conclusion of unit verticality was determined to be the root cause of the issue.

Identification and evaluation of rolling element bearing failures using  fluid, filter, and material analysis techniques [Conference | Conférence]

Typical rolling element bearing wear modes have been characterized in terms of materials used in bearing construction, typical wear debris size and morphology.  Characterization data has been collected from field data, and test rig data. In field applications, the lubricating oil containing the wear debris proceeds through the lubrication system, and often passes over chip detectors or magnetic plugs which capture a small percentage of debris.  Often, lubrication systems utilize high efficiency filters capable of capturing particles greater than 3-10 microns in size. Therefore a large percentage of the remaining wear debris from the rolling element bearing wear mode is captured in the filter element. This poses a problem to use of common methods of laboratory fluid analysis, as the debris representing the wear mode is commonly trapped in the oil filter. Furthermore, common methods of laboratory fluid analysis are not sensitive to the debris released during these wear modes. Therefore, for multiple reasons, traditional oil sampling doesn’t accurately and reliably reveal rolling element bearing wear modes. New methods of fluid, filter and material analysis exist that provide sensitive, unambiguous, and statistically reliable information regarding rolling element bearing wear modes. This information can be used to schedule maintenance and avoid unplanned downtime. This presentation discusses: 1) Characterization of rolling element bearing failure modes; 2) Fluid, filter, and material analysis techniques, and  technique limitations; 3) Fluid, filter and material analysis strategies; 4) Case studies.

Fluorescence Spectroscopy for Online Condition Monitoring of Machinery Lubricants [Conference | Conférence]

Lubricating oils contain antioxidant additives in order to protect the base oil from thermal oxidation, thereby preventing loss of lubricity and formation of oxidation products and deposits such as sludge and varnish. Monitoring the antioxidant levels provides early indication of oxidative degradation of the lubricant, allowing for condition-based maintenance ahead of potential damage to the equipment. This translates to lower cost of maintenance and improved equipment availability, which are key drivers for the power generation industry. Current techniques for measuring antioxidant additive content require expensive laboratory grade equipment, sample preparation, consumables and operation by trained personnel, making them unsuitable for online monitoring. This presentation discusses the application of an alternative technique using fluorescence spectroscopy technology that allows for real-time, online monitoring of antioxidant additive levels.

Predictive maintenance via current and voltage monitoring. [Conference | Conférence]

The diagnostic solution can be used together with a vibration monitoring system as a complementary tool for detecting electrical faults. Alternatively, it can be used where dedicated vibration monitoring is not practical, economical, or comprehensive enough. It can detect changes in the load the motor is experiencing due to anomalies in the driven equipment or process such as cavitation or plugged filters and screens. Since it doesn’t require any sensor installation on the motor itself or on the associated load, The MCM is especially attractive for inaccessible driven equipment and is applicable to most types of pumps, compressors, and similar loads. It is also well suited to the monitoring of submersible, borehole, downhole, and canned pumps.

Maintenance prédictive via la surveillance du courant et de la tension. [Conference | Conférence]

La solution de diagnostic peut être utilisée en parallèle avec un système de surveillance vibrations comme outil complémentaire pour détecter les défauts électriques. Alternativement, il peut être utilisé où la surveillance des vibrations dédiée n’est ni pratique, ni économique, ou tout simplement impossible. Le système détecte des changements de charge exercés au moteur qui sont de liés aux défauts de l’équipement entraîné ou de mauvais procédés tels que la cavitation ou  des filtres/écrans obstrués. Puisque le système ne nécessite aucune installation de capteur sur le moteur lui-même ou sur les composants associées, le MCM est particulièrement attrayant pour les équipements entraînés inaccessibles et s’applique à la plupart des types de pompes, compresseurs et de charges similaires. Il est également bien adapté à la surveillance de pompes submersibles, de forage, de fond de trou et rotor noyés.

Modal Testing and Transient Vibration Analysis Applied to Fan Vibration [Conference | Conférence]

Operating deflection shape analysis, modal testing and transient vibration analysis techniques are complementary to standard vibration testing to determine the source of vibration problems.  A quick review is given of these advanced techniques, and then two case studies are presented in which these techniques were used to determine the source of vibration problems. One problem was with underground booster fan with VFD’s.  When the speed approached the maximum speed, the vibration increased to an unacceptable level.  Since the vibration was highest in the axial direction on the existing accelerometers, and the design calculations did not predict any resonance, it was thought was that a local resonance may have resulted in a high vibration reading.  The testing determined that an overall axial resonance was present. In the second case, during the startup of a centrifugal fan it was found that the vibration level at operating speed was extremely high.  Trim balancing revealed that balance could be achieved with weights from 1/6 to 1/10 of that suggested by the balancing software.  When these weights were installed, the vibration level was still extremely variable from day to day.  The initial hypothesis was a rocking mode of the foundation fan system.  Testing revealed a rotor one nodal line resonance when the rotor was stationary at just above operating speed.  Since this testing does not account for the fluid film stiffness in the hydrodynamic bearings, nor the gyroscopic effects of an operating rotor the resonant frequency during operation was not known.  However, transient testing revealed a 60° phase shift and a high vibration increase at startup.  Put together, these revealed a rotor resonance just above operating speed.

Predicting system natural frequencies from machine speed trials where multiple operating frequencies are present. [Conference | Conférence]

The prediction of excitation of component or system natural frequencies is often a challenge. Original design finite element analysis results may not be available or the analysis may not have been performed at all. Forced response testing can reveal system or component natural frequencies, but not all frequencies may be revealed, and of those revealed, not all may be excited. Machine speed trials can often be used to reveal resonant excitation of operating frequencies present, however this method is limited by the current machine speeds. This paper describes a method for predicting excitation of system natural frequencies using forcing functions from existing operating equipment in machine speed trials where multiple forcing frequencies are present and the speed range of interest is outside of the operating range. Actual data will be shown to illustrate this situation.

Acoustical case studies of hydro-electric generators and turbines and relations between acoustics and vibration measurements [Conference | Conférence]

In power plants, acoustical signals are generally easier to measure than vibration signals at specific location because the security procedure restrict the installation of accelerometers during the operation of the hydro-electric group. Specific acoustical measurements has been developed at the Hydro-Québec research center to set some maintenance actions or to gain more information about the operating conditions of the Hydro-electric groups. These include airborne pressure measurements with conventional microphones for the generators to make some relation with the   vibration or electromagnetic signals and to verify with the operating standard of the hydro-electric groups and also more specialised acoustical intensity measurements for mapping the generator floor to understand the emission pattern of the generator. Other specific measurements are related to the rotor of the generator with microphones inside the rotor. All these acoustical measurements are interpreted in term of operating conditions and specific frequencies. Other acoustical measurements are performed to assess the runner cavitation erosion. These measurements are based on method developed at the Hydro-Québec research center. It is possible to predict cavitation erosion with some airborne measurements performed outside of the runner. This presentation will show every type of these acoustical measurements that were performed over the years on several hydro-electric groups. The main goal of these measurements is to make some multiphysics links between the acoustic, vibration and electromagnetic. The presentation will show some results and interpretations related to maintenance and knowledge of the hydro-electric groups.

Études de cas acoustique d’alternateurs hydro-électriques et de turbines et relations entre les mesures acoustiques et vibratoires [Conference | Conférence]

Dans les centrales hydroélectriques, les signaux acoustiques sont généralement plus faciles à mesurer que les signaux de vibration à un emplacement donné, car la procédure de sécurité limite souvent l’installation d’accéléromètres pendant le fonctionnement du groupe hydroélectrique. Des mesures acoustiques spécifiques ont été développées au centre de recherche d’Hydro-Québec pour définir des actions de maintenance ou pour obtenir plus d’informations sur les conditions de fonctionnement des groupes hydroélectriques. Celles-ci incluent des mesures de pression avec des microphones classiques pour établir une relation avec les signaux de vibration ou électromagnétiques et vérifier la conformité aux normes de fonctionnement des groupes hydroélectrique, ainsi que des mesures d’intensité acoustique plus spécialisées permettant de cartographier l’émission de l’alternateur. D’autres mesures plus spécifiques concernent le rotor de l’alternateur utilisant des microphones à l’intérieur du rotor. Toutes ces mesures acoustiques sont interprétées en termes de conditions de fonctionnement et de fréquences spécifiques. D’autres mesures acoustiques sont effectuées pour évaluer l’érosion par cavitation de la turbine. Ces mesures sont basées sur une méthode développée au centre de recherche d’Hydro-Québec. Il est possible de prévoir l’érosion causée par la cavitation avec certaines mesures de pression sonores effectuées à l’extérieur de la turbine. Cette présentation présentera tous les types de mesures acoustiques effectuées au fil des ans sur plusieurs groupes hydroélectriques. L’objectif principal de ces mesures est d’établir des liens multiphysiques entre la vibration, l’acoustique et l’électromagnétisme. La présentation montrera quelques résultats et interprétations liés à la maintenance et à la connaissance des groupes hydroélectriques.

Strain Gauge Testing on Various Applications [Conference | Conférence]

A client asked Acuren to provide strain data during destructive testing of a dryer can at the manufacturers shop. Acuren provided installation and monitoring of two individual tests on separate dryer cans of different metallurgical composition.  Both were tested to failure safely with excellent data and some spectacular visual results.

The client had been manufacturing the product for years with the same process. When challenged with making a product that would withstand more pressure, they opted to document the test procedure more than they have in the past. Having worked closely with Acuren previously with excellent results on other projects, they contacted us to arrange this testing at their site.

Another client requested strain gauges to be attached to a test rig while testing a precast concrete girder to failure ensuring the safe testing of the item.

Another example of this services was when a client required continuous monitoring of a critical lift and had to ensure an improvised support did not fail while a crane’s outrigger was being supported by a piece of structural steel placed under the floor directly beneath the crane.

All these requests were all very interesting projects in their own unique way and hopefully this presentation will shed some light on how useful this type of testing can be.

Motion Amplification: Case Studies and Innovations [Short training | Mini-formation]

Motion Amplification (MA) is a video-processing technique that detects subtle motion and amplifies that motion to a level visible to the naked eye. Videos created through Motion Amplification enhance the understanding of the components and interrelationships creating the motion. Every pixel in the camera becomes a sensor, creating millions of data points in an instant, all in phase with one another. This new tool has been available recently as an addition to the predictive maintenance arsenal.  Innovations in image processing algorithms are being developed currently.  The current training is aimed at summarizing the current state-of-art and explaining the most recent developments. Supported by case studies and examples, we will look at absolute shaft movements that can now be quantified, in addition to measuring the rpm.  Another useful tool that has been created is the method for creating clear shaft inspection images. Shaft runout and vibration measurements are traditionally difficult to obtain, requiring the installation of permanent displacement probes, and even then, glitch can be a large factor.  So with this optical solution, we can now look at rotating shafts, pulleys and couplings, and obtain measurements and information never before possible.

Études de cas et innovations en amplification des mouvements [Short training | Mini-formation]

L’amplification de mouvement (MA) est une technique de traitement vidéo qui détecte les mouvements subtils et les amplifie à un niveau visible à l’œil nu. Les vidéos créées via l’amplification de mouvement améliorent la compréhension des composants et des interrelations créant le mouvement. Chaque pixel de la caméra devient un capteur, créant des millions de points de données en un instant, tous en phase les uns avec les autres. Ce nouvel outil vient d’être ajouté à l’arsenal de maintenance prédictive. Des innovations dans les algorithmes de traitement d’images sont en cours de développement constante. La formation en cours vise à résumer l’état actuel des connaissances et à expliquer les développements les plus récents.

Illustrées par des études de cas et des exemples,  nous allons regarder les mouvements absolus de l’arbre qui peuvent maintenant être quantifiés, en plus de la mesure du rpm. Un autre outil utile créé est la méthode permettant de créer des images d’inspection claires des arbres. Les mesures de déplacements et vibrations d’arbre sont traditionnellement difficiles à obtenir, nécessitant l’installation de sondes de déplacement permanents, et même dans ce cas, l’erreur de mesure peut être un facteur important. Ainsi, avec cette solution optique, nous pouvons maintenant examiner les arbres en rotation, les poulies et les accouplements, et obtenir des mesures et des informations jamais possibles auparavant.

How to Balance IIoT with Existing Predictive Maintenance Programs [Conference | Conférence]

While implementing IIoT-based condition monitoring systems can greatly improve your operational efficiency and predictive maintenance program, most facilities already have established maintenance practices for existing equipment and implementing new IIoT based systems requires dramatic changes to workflows and established processes. Rather than reinventing your maintenance routine, the solution is to balance these systems with existing resources and workflows. To demonstrate how organizations are adapting to the IIoT revolution, we will present 2 cases examples where maintenance and reliability teams identified troubled assets with traditional route-based vibration monitoring and used continuous cloud-base vibration monitoring systems to continually monitor once a problem was identified. With this approach, both facilities were able to continue operating confidently while avoiding premature replacement of the asset. With continuous monitoring the facilities were able to plan for repairs during the next scheduled outage. Lastly, we will present a method to determine how to prioritize assets for potential IIoT implementation or where to start a pilot program based on the asset’s risk of potential failure, impact of that failure and duration of any potential downtime.

Condition Monitoring & IIoT [Conference | Conférence]

The business of condition monitoring has taken many twists and turns over the past decades.  As the industry is moving towards new IIoT (Industrial Internet of Things) technologies and methodologies, what is the relevance of traditional condition monitoring? The condition monitoring industry has established tried and proven methods for detecting failures and for finding ways to prevent downtime.  The equipment in factories is safer, more efficient, and more reliable as a direct result of the condition monitoring practices that have been applied over the past 40 years.   Are these practices going to be displaced by IIoT?   Will the standards of vibration and condition monitoring be relevant in a digitized factory?  Will IIoT effect the training and certification of personnel within our organizations?  Are advances in machine learning going to change the way that we find defective components in machinery?  How will IIoT effect condition monitoring service companies? These questions will be challenged in an open manner during the presentation.  An overview of the current state of IIoT sensors, communication software and service structures will also be presented. Participants will be encouraged to offer their perspectives on the subject during this open discussion.

Case Studies in Vibration Diagnostics and Correction. [Conference | Conférence]

There are many techniques available for diagnosing probable root-cause of vibration that adversely affects the reliability of an asset, including time waveform and frequency analysis, natural frequency testing, operating deflection shape (ODS), vibration video amplification (VVA), and finite element analysis (FEA). Once the source of a vibration problem has been diagnosed, a Corrective Action Plan must be developed and implemented.  Vibration control methods include force reduction/elimination, resonance tuning, damping and dynamic vibration absorbers. Case studies will be used to show how these vibration diagnostic and control methods can be used to reduce vibration, increase fatigue life, and increase the reliability of mechanical equipment and structural supporting systems.

Monitoring of uneven magnetic pull for controlling vibration of rotating machinery [Conference | Conférence]

Uneven Magnetic Pull (UMP) plays in important role in increased vibration of rotating parts in electric motors. Besides the influence of mechanical parameters like mass unbalance, misalignment, stiffness, eccentricity, bending, natural frequency and even fluid dynamics in vibration of a rotor in the electric machine, UMP is also common causes for increased vibration and is a popular topics for engineers and academics to study on. Sometimes a well-balanced and aligned rotating machine, i.e. electric motor, experiences vibration once it is put into operation. The reason is that besides all the mechanical forces that are affecting the rotating part of the motor, there is one important factor with an electrical nature: Magnetic Pull. Uneven Magnetic Pull (UMP) affects rotor vibration as strong as a mass unbalance does. Monitoring the magnetic pull inside the motor core is a vital step in performing predictive maintenance programs for industrial plants, because any minor changes in the magnetic pull can be easily detected, identified and fixed before it leads to a catastrophic shutdown. There are some studies on the modelling and calculation of magnetic pull in the air gap of electric machines but in practical applications such a modelling is not possible because the number of stator slots, slot width, rotor bars, air gap, and other critical data are not known. In this paper we study a practical method to monitor the magnetic pull and detect UMP and to get an insight of what is really happening inside motor core where the rotor is subjected to the strong magnetic field of electric motor. We also describe the effects of Uneven Magnetic Pull (UMP) on the vibration of rotating machines and the methods to identify, measure and demonstrate it.
